Abstract

The performances of alumina-supported Group VIII metal catalysts promoted by Mo-Na 2O in the synthesis of alcohols from syngas were examined. The activity for alcohol synthesis at 255°C decreased in the order Rh>Ir>Ru>Pd>Ni>Pt>Cu>Co>Re>Fe. The highest activity for alcohol synthesis was achieved with 3% Rh−5% Mo−1.25% Na 2O/Al 2O 3 (480 g/l cat·h); however, this catalyst showed a rapid decay in activity. Ir-Mo-Na 2O and Ru-Mo-Na 2O catalysts also had a high activity for alcohol synthesis and did not show any decay during the period of the experiments.
